Nassau County police are investigating a violent encounter involving two Cedarhurst gas station store clerks and two customers as a possible bias incident. Detectives say the two customers who threatened to take the life of one of the workers remain on the loose.

Investigators say the melee was caught on surveillance video inside the gas station Saturday night around 9:45 p.m.

It involved a store clerk who was fighting to protect himself after a male and female customer allegedly began to yell and curse at him and another employee with anti-Muslim slurs.

“She was telling him, ‘Kill him, kill him, kill him.’ That's what she was saying," says the owner of the gas station, who did not want his face shown. He says he is furious about what took place.

Detectives say the violence started when the female customer began to throw miscellaneous food item at the clerks.

The surveillance video shows one of the clerks fighting back by throwing items at the two, with the male customer then allegedly throwing anything he got his hands on.

“The male suspect then attempted to throw a six-foot metal rack at the complainant and then threw two anti-freeze bottles at the store clerk, thus striking him. However, no injuries were reported at this time,” said Nassau County Police Det. Lt. Richard Lebrun.

Police say before anything physical was thrown, the male and female customers initially began to yell and curse when the victim was unable to make a slushy drink that the store usually carries.

While no arrests have been made, police are hoping to track down the two who are believed to have gotten away in a dark four-door sedan headed northbound on Rockaway Turnpike.

Nassau County detectives are asking anyone who might have information about this case to call the Crime Stoppers hotline at 1-800-244-TIPS.
